NCP1605DR2G Description

Short technical summary and product information.

The NCP1605DR2G from On Semiconductor is an integrated circuit designed for Power Factor Correction (PFC) applications. It operates in Discontinuous Conduction Mode (DCM) or Critical Conduction Mode (CRM) to achieve near-unity power factor.

 

Key electrical specifications include an operating voltage range of 10V to 20V and a switching frequency of up to 250 kHz. The device offers a drive capability of -500 mA / +800 mA and an operating current of 12 mA. It also features various safety functions such as output under and overvoltage protection, brown-out detection, soft-start, overcurrent limitation, zero current detection, thermal shutdown, and latched off capability.

 

Packaged in a 16-SOIC (0.154", 3.90mm Width) surface mount configuration, the NCP1605DR2G is suitable for applications requiring robust and compact PFC stages. Its operating temperature range is -55°C to 125°C (TJ).

 

Typical applications include PC power supplies and all off-line appliances that require power factor correction. The circuit integrates skip cycle capability for reduced standby losses.
